He faces a mandatory minimum sentence of five years in prison after admitting he used his home computer to receive and transmit images of minors engaging in sexually explicit conduct. Federal prosecutors were seeking more than seven years, the South Florida Sun Sentinel reported.

Mangione had been free on bail but was ordered taken into custody after the plea.

His sentencing was scheduled for 2:30 p.m. at the West Palm Beach federal courthouse.

The 51-year-old Mangione ran ICE's South Florida operations from 2007 to 2011, including numerous child pornography investigations. A 27-year veteran of the agency and its predecessors, he retired a few months after investigators searched his home and office computers in April 2011.
